Mass., a corporation of Massachusetts Application March 16, 1946, SerialNo. 654,903 1 Claim. (Cl. 20.6-45.34)

This invention relates to a package and method of making the same.

One object of the invention is to provide a novel package constructed todisplay and preferably to visibly display the packaged commodity, whichmay be economically produced and whose construction is sufficientlyrigid to withstand handling during commercial shipment and use.

A further object of the invention is to provide a novel, eflicient andeconomical method of producing the present novel package.

With these general objects in view, and such others as may hereinafterappear, the invention consists in the package and method of making thesame, and in the various structures, arrangements and combinations'ofparts hereinafter described and particularly defined in the claim at theend of this specification.

In the drawings, Figs. 1 to 4 illustrate in perspective successive stepswhich are preferably employed in the formation of the lined carton in acondition ready to be filled with the commodity to be packaged; Fig. 5is a perspective illustrating the filled carton just prior to theformation of the top closure therefor; Figs. 6, 7 and 8 are details inperspective illustrating the positions occupied by the flaps and topclosure during successive steps in the formation of the package; andFig. 9 is a perspective illustrating the completed package.

In general, the present invention contemplates a novel construction ofpackage comprising a bag rectangular in section for containing thecommodity to be packaged. The bag may and preferably will be formed ofany of the usual or preferred bag forming materials such as parchmentpaper, but preferably the bag is constructed of cellophane or otherrelatively strong transparent paper. The top of the bag is closed afterthe bag has been filled, by an elongated closure, preferably of thepull-put type, which is I folded down onto the upper surface of the bag,

providing triangular end tabs which are subsequently folded inwardly. Inorder to protect the bag to enable it to be satisfactorily handledduring shipment without breakage, a sleeve of relatively stiffer,stronger and heavier sheet material, such for example as carton boardforming material, is wrapped about the bottom, two sides and the top ofthe bag so as to leave the two side panels of the bag unprotected andthrough which the packaged commodity is visible for display purposes.The sleeve may and preferably will .be formed by an elongated strip 2 ofthe stifler board forming material, and as it is wrapped about thebottom and two sides of the bag, the ends of the strip are folded 111-,

wardly upon the top of the upper surface of the bag, preferably intooverlapping relation and with one of the triangular end flaps of the topclosure interleaved between the contacting surfaces of the overlappedportions of the strip. The overlapping ends of the strip are adhesivelysecured to one another providing a completed package which may beeconomically manufactured and handled during shipment and use exactly asan ordinary lined package. In addition, the construction of the packagelends itself to convenient opening and the retention of the top closureof the bagv in such condition that it may be subsequently closed topreserve the contents of the package.

Referring now to the drawing, the successive steps -by which the presentpackage may be produced in a condition ready to be filled areillustrated in Figs. 1 to 5. The bag is preferably f rmed y bein wrappedabout a forming block In in the manner illustrated in Fig. 1, the sideseam I! being overlapped upon the opposed panel and adhesively securedthereto. The bottom of the bag may and preferably will be closed by anyusual or preferred type of closure, preferably by an elongated pull-outtype of closure I6 with the triangular end tabs l'l, I8 folded towardone another and uponthe bottom of the bag, as illustrated in Fig. 3. Thebag in this condition and while supported upon the mandrel ID, haspreferably secured to it the bottom and side forming panels 20, 22, ofthe strip of carton board forming material or other relatively strongsheet material, as by being spot glued, as at 33, to the bottom andopposite sides, and in the preferred method the strip is arranged tocover the side scam I 2 of the bag. Thereafter the bag with the stripmay be removed from the forming block, producing the structureillustrated in Fig. 4. In this condition the opened bag with itsattached strip may be filled with the commodity to be packaged, beingcapable of being handled in any of the standard filling machines nowupon the market and which are adapted to handle rectangular cartons.

After the filling operation has been completed, provision is made forclosing the top of the bag,

and for this purpose the portions 24, 26 of thetwo sides of the stripprojecting above the score line defining the top of the body of thepackage may be folded outwardly and the top of the bag .closed by anelongated pulled out closure 2| formed in any of the standard topclosing machines now used for producing this type of a closure. Theupstanding tab 29 of the closure is folded upon itself and then downupon the top of the bag, providing triangular end tabs 30, 32 whichproject onto the outwardly projecting portions 24, 26 of the strip inthe position shown in Fig. 7. Preferably one projecting portion 24, ofthe strip is folded inwardly, folding the triangular end tab 30 of thebag over upon the top of the bag and then the second projecting portion25 of the strip and the second end tab 32 are folded over upon thepreviously folded down portion 24 of the strip thus interleaving thetriangular end tab between the overlapping portions of the strip andanchoring the bag to the protecting sleeve thus formed. The portions 2t,26 of the strip, as shown in Figs. 6 and 7, are provided with adhesiveII for securing the overlapped portions of the members 24, 26 together.

From the description thus far it will be observed that the presentpackage is attractive in appearance, and utilizes a minimum amount ofthe heavier carton forming board. The protecting sleeve imparts rigidityand strength to the package enabling it to successfully withstandshipment and handling. The fact that the two opposed wide side panels ofthe bag are uncovered by the sleeve and therefore exposed adds to theutility of the package for display purposes, as in those instances wherethe bag is constructed of transparent material such as cellophane thepackaged commodity is clearly visible through such transparent sidepanels of the package.

While the illustrated package comprises the preferred embodiment of theinvention, it will be understood that other forms of top closures forthe bag may be utilized and that the protective sleeve may take otherforms, within the scope of the following claim.

Having thus described the invention, what is claimed is:

As a new article of manufacture, a package 4 comprising a bag containinga commodity, said bag being formed to provide a closed rectangularbottom and four rectangular side walls and having its top folded toprovide a top closure, said closure comprising outwardly extendingflaps, and an outer sleeve of an elongated strip of a relatively heavystiff material of substantially uniform width substantially equal to thewidth of certain side walls of said bag, said sleeve being of a sizesnugly embracing the bottom, top and two opposite of said certain sidewalls of the bag whereby the free edge portions of said sleeve liesubstantially in the same planes as the exposed walls of said bag, saidsleeve having end portions extending across the top of said bag inoverlapping relationship and having one of said closure flapsinterleaved between the said overlapping end portions, said overlappingend portions being adhesively secured to each other.
